Hi.. Thank you for your reply. This EJB work with JBoss 4.2.3 GA and does not work with JBoss 5.0 GA | package com.test.model.ejb.system; | | import com.test.model.entity.system.Usr; | import javax.ejb.Stateless; | | @Stateless(name = "UsrEJB") | public class UsrEJBBean implements UsrEJB, UsrEJBLocal { | @PersistenceContext(name = "testPU") | EntityManager em; | | public UsrEJBBean() { | } | | public Usr persist(Usr usrEntity) { | em.persist(usrEntity); | return usrEntity; | } | } It does not give any error, just warnings but it does not bind EJB to JNDI Tree like JBoss 4.2.3 GA.
